The present invention is generally directed towards a polycarbonate surface having an ink printed on the surface. The ink adheres to the polycarbonate and is compatible with a hard coat applied to the polycarbonate substrate. The ink comprises a polycarbonate or a polyester resin or an acrylic resin. The ink composition also comprises a blend of polycarbonate ink or an acrylic ink with a polyester ink such that the ink adheres to the polycarbonate substrate on subjecting the substrate to water immersion and cataplasma tests.
